    thanks for all the replies.

    before I try anything, would you say that the machine should be able to run photoshop without any problems?
    it is the latest version of photoshop from creative cloud.

    I also wonder if the machine would run better with the previous OS?

    thanks

    You’re welcome Randy, no point in reinventing the wheel. I am of the same mind as you, there is nothing wrong with the configuration. Photoshop should not be too much to handle. On its own anyway.

    It should be able to run Photoshop just fine. Besides, you mentioned problems with opening other applications too, so it's logically not a Photoshop problem.

    A different version of the Mac OS will make no difference whatsoever (assuming that everything is okay with your current installation; but I highly doubt that this is an OS-related problem).

    NO MAC made in the last 10 years, of any configuration, should be acting the way yours is unless there is something wrong with it. You need to troubleshoot and track down that problem and fix it.

    The solution will likely be very simple. You just have to meet me halfway and do the things that I suggested, in the order that I suggested them.

    Trust me, I've dealt with this problem more times than I can count, and I've never yet been unable to figure out the problem and suggest a workable fix. That's why I created an entire Web site to deal with this sort of problem.

    If so far nothing obvious can be found to explain the slowness...I would recommend looking more closely into to what moderator Slydude mentioned in post #11 of this thread. If this iMac has a "rogue" application or activity running...best to launch the Activity Monitor utility app...click on the "CPU" tab...and look thru the list to see if something is using up an unexpected amount of CPU resources.

    If nothing can be found there...then things may come down to the fact that this is an entry level 2017 iMac...with a slower "spinner" hard drive. Looking at the CPU benchmarks for this 2017 iMac...the CPU numbers aren't tremendously better than my 2011 MacBook Pro:

    - 2017 21" iMac = 12356
    - 2011 17" MacBook Pro = close to 10,000

    The last thing I would mention is...how many apps or activities are going on simultaneously on this iMac? If too much is going on at the same time...this could be over-taxing the iMac's CPU, GPU, and RAM.

    I'm sure this is covered on Randy's page too but I am in favour of checking CPU use with Activity Monitor. If something or somethings are using up large amounts of the CPU resources they can be forced to quit from the AM interface which is an easy way to eliminate possibilities.
    The other thing high on my list is "Login Items". Many new apps like to install helper tools or run in the background all the time. You can safely remove pretty much all of these items as they start up when you launch the app anyway.

    any help would be massively appreciated. hoping I haven't wasted £1200 on this "new" iMac.
    If you system is clean from any malware etc.. I suggest to install more RAM. Before you do that try to backup and then format, reinstall all. If still slow only with Photoshop, I'm pretty sure installing more RAM will help. Also booting from a 500GB SSD, which non expensive today, will fly even with photoshop since I did it with one of my customer.

    One of the difficulties witrh the 21`.5" model is Apple considers them to be non-user upgradeable and memory comes pre-installed with only 8 or 16GB options. To increase memory requires a full tear down of the iMac to access memory. The 27"model still com es with the rear hatch and is easy accessible.
    Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    Though worth checking, Malware is almost never the cause of a recent slowdown on a Macintosh.

    Unless a user has an abnormally small amount of RAM installed in their Macintosh (e.g. they have one of the older Macs that came with only 2GB of RAM), adding more RAM is never the answer when a Mac user experiences a recent slowdown.

    That is excellent advice for a Windows user. Mac users should almost never need to do a full erase and re-install of all of their software. That is not a Macintosh solution.

    The original poster stated that he was having problems with multiple applications.

    Yes, switching from a rotating disk hard drive will speed up a Mac, especially loading apps. However, if any particular Mac used to run fine, but now has become slow, unless the hard drive is failing, adding an SSD is not a solution to a recent slowdown.
